Water outlet mechanism

Abstract

The present disclosure discloses a water outlet mechanism comprising a water outlet body, a driving assembly, an eccentric cam, a swinging plate, and one or more water outlet nozzles. The water outlet body comprises a water inlet port, a water outlet port, and a water-passing cavity in communication with the water inlet port and the water outlet port. The driving assembly is disposed in the water-passing cavity. The eccentric cam is rotatably disposed in the water-passing cavity and is operatively coupled to the driving assembly. The swinging plate is swingingly disposed in the water-passing cavity and is operatively coupled to the eccentric cam. The one or more water outlet nozzles are swingingly disposed on the swinging plate and are configured to be driven by the swinging plate to perform reciprocating movement of swinging in a front-and-rear direction.

What is claimed is: 
     
         1 . A water outlet mechanism, comprising:
 a water outlet body,   a driving assembly,   an eccentric cam,   a swinging plate, and   one or more water outlet nozzles, wherein:
 the water outlet body comprises a water inlet port, a water outlet port, and a water-passing cavity in communication with the water inlet port and the water outlet port, 
 the driving assembly is disposed in the water-passing cavity, 
 the eccentric cam is rotatably disposed in the water-passing cavity and is operatively coupled to the driving assembly, 
 the swinging plate is disposed in the water-passing cavity and is operatively coupled to the eccentric cam, 
 a bottom side of the swinging plate comprises one or more swinging matching grooves, 
 each of the one or more water outlet nozzles comprises a swinging shaft, and 
 the swinging shaft is swingingly disposed in a corresponding one of the one or more swinging matching grooves to enable the swinging shaft to move synchronously with the swinging plate and is configured to be driven by the swinging plate to enable each of the one or more water outlet nozzles to perform reciprocating movement of swinging in a front-and-rear direction. 
   
     
     
         2 . The water outlet mechanism according to  claim 1 , wherein:
 a direction of reciprocating movement of the swinging plate is the same as a direction of the reciprocating movement of each of the one or more water outlet nozzles.   
     
     
         3 . The water outlet mechanism according to  claim 1 , wherein:
 the swinging plate comprises a transmission slot operatively coupled to the eccentric cam, and   an eccentric portion of the eccentric cam is disposed in the transmission slot, so that the swinging plate is driven to perform reciprocating movement in the front-and-rear direction when the eccentric cam is rotated.   
     
     
         4 . The water outlet mechanism according to  claim 1 , wherein:
 the water-passing cavity comprises a position-guiding groove in the front-and-rear direction for guiding movement of the swinging plate,   the swinging plate comprises a protrusion extending in the front-and-rear direction, and   the protrusion is placed in the position-guiding groove and is configured to perform reciprocating movement in the front-and-rear direction along the position-guiding groove.   
     
     
         5 . The water outlet mechanism according to  claim 1 , wherein:
 the swinging plate further comprises one or more nozzle-limiting grooves extending through the swinging plate in a vertical direction, and   a top end of each of the one or more water outlet nozzles extends into a corresponding one of the one or more nozzle-limiting grooves.   
     
     
         6 . The water outlet mechanism according to  claim 1 , wherein:
 the driving assembly comprises an impeller, a speed reducer, and a rotating shaft,   the impeller, the speed reducer, and the rotating shaft are sequentially connected together,   the impeller is adjacent to the water inlet port,   the rotating shaft is adjacent to the water outlet port, and   the rotating shaft is connected to the eccentric cam.   
     
     
         7 . The water outlet mechanism according to  claim 6 , wherein:
 the water outlet mechanism further comprises a diverter,   the diverter is located in the water-passing cavity and covers a periphery of the impeller, and   the diverter comprises one or more oblique inlet openings.   
     
     
         8 . The water outlet mechanism according to  claim 3 , wherein:
 the transmission slot is rectangular having two long sides and two shorter sides, and   when the eccentric portion of the eccentric cam contacts the two long sides of the transmission slot, the eccentric portion drives the swinging plate to perform the reciprocating movement in the front-and-rear direction.
